Revert "PCI: tegra: Use PCI_CONF1_EXT_ADDRESS() macro"

This reverts commit dc74cf19b50fd34a769c52d1a6c73b0c80e39787.

Commit dc74cf19b50f ("PCI: tegra: Use PCI_CONF1_EXT_ADDRESS() macro")
updated the Tegra PCI driver to use the macro PCI_CONF1_EXT_ADDRESS()
instead of a local function in the Tegra PCI driver. This broke PCI for
some Tegra platforms because, when calculating the offset value, the mask
applied to the lower 8-bits changed from 0xff to 0xfc.

For now, fix this by reverting this commit.
